Actually, this does explain what I’m seeing and your result is pretty spot on with what I’m reading.

I’m not sure what the temperature coefficient is for this device and the data sheets are lacking in that respect. Rather than use rules of thumb which you may or may not understand, you should first look at the data sheet of the part you’re using.
At least at no load or very small load the LDO regulator will be way more efficient. Try to find a datasheet for your specific zeners which shows the breakdown characteristics.

If you include the dynamic resistance in the model, you must use a lower voltage for the ideal zener.
Even if it specified at 70mA, there is going to be some there and in this case it is not negligible therefore it must be incorporated in to your circuit model, that why your circuit analysis provides a different answer but adding dataxheet zener resistance to the model gives a solution that approaches more closely your result.
Due to possible 1n429 of exchange rate update, price in various currencies is for reference only. Actually, it was a candidate for a regulated supply fed by a CCS.
In fact, as I increase and decrease the resistor value, the Zener voltage increases and decreases along with it. The next problem is that at 70mA and 4 volts, the power is 0.
View Cart 0 items. How much current fatasheet th load require? Can you expand on dwtasheet statement: The dynamic resistance of the Zener may not be able to drop low enough, even with 70mA available to it, to make the proper resistor divider equivalent for the node to be equal to 3.
Therefore a better model of the zener diode is the zener diode plus the zener resistance in series. WhatRoughBeast 49k 2 28 You can also buy SquareTrade Protection Plan for the products:. Reference Currency HKD What output volta de you require?

The closer to the minimum input voltage the more difficult it will be to avoid datassheet changes in current flowing through the TL Sign up using Facebook. In my experience, low-voltage zeners anything below 5V all seem to have a very soft ‘knee’ and not particularly ‘vertical’ current-vs-voltage curve.
This datashedt was simply to highlight my dismay at how poor these zeners really are! No load except for the DMM. As I pointed out in my query, I used the test currents from the relevant datasheets as a guide. Is that the dynamic resistance of the zener? Both Zeners came from separate suppliers.

I have a question about the regulation accuracy or lack of of a 3V6 Zener diode. You don’t dataseet what you saw there. As shown in the circuit below which models the behavior that you are seeing of a voltage reading of about 4V from the zener diode simulate this circuit — Schematic created using CircuitLab.
Zeners are notoriously power inefficient even at no load. For use in stabilizing and clipping circuits with high power rating. The problem is how you are modeling your circuit, because the series resistance you are using is so close the zener resistance, it must included in the circuit model. It seems odd then that the datasheets would specify an Izt of 69mA if it didn’t show the zener in the best light. Email Required, but never shown. The dynamic resistance describes the small-signal behavior near the test current.
I suppose the point is, at 70mA, according to the datasheet, the voltage across the zener should be 3. I suspect that if you retest the “1N” parts with a test current of something like 20mA 70 ohms you may find that they’re within spec voltage-wise. It’s like the Zener resistance isn’t decreasing as the current increases, which is not what I’d expect. Integrated Circuits Short Description: The ones with voltage of 5.
